The DELPHI AF10275-12B1 Mass Air Flow (MAF) sensor is engineered to precisely measure the volume and density of air entering the engine's intake system. This critical data is then sent to the engine control unit (ECU) to determine the correct amount of fuel to inject for efficient combustion. By providing accurate airflow readings, this sensor plays a vital role in maintaining optimal engine performance, fuel economy, and emissions control. A malfunctioning MAF sensor can lead to poor acceleration, rough idling, increased fuel consumption, and illuminated check engine lights. DELPHI is a trusted brand known for its commitment to quality and reliability in automotive components. This MAF sensor is designed to meet or exceed original equipment specifications, ensuring a proper fit and dependable operation for your vehicle.
